To all whQm it may concern:

Be it known that 1;"Fnnn hjDin rINsoN, a citizen of the Dom nion ofCanada, reslding lat l-lydro,inthe eoun'ty of Blaine and StateofjMontana, 'have'invented certain new and nseful Improvements inCollapsible Churn- .TFrames, :of

which theffollowing is a specification. I k

This invention relates .to supporting frames, and more particularly tocollapsible framesfor su porting churns and similar vessels.

' The object offtheinvention is to provide ,a] si mply constructed andstrong frame jof this character which may be quickly and easily setupand collapsed without theuse of tools. 7

Another .object is to provide a frame of this-character, the braces ofwhich when in :open operative position securelyand reliably hold theframe inupright position against .collapsejand canlonly beffolded afterthe locking bar constituting a art of the frame is; released.

t-view,,.,\ vhich will appearas the description ?With the [foregoing andother objects in proceeds, theinyention resides in the combination; andarrangement of parts and inthe deta ls of. constructlon hereinafterdescr bed and cla med, t be ng understood, that ,c flng nin-the pr iembodiment Ofth invention herein disclosed be niacie within the scope ofwhat is cla med ,wlthout departing from; the. spirit of .thejinvention.

In thelacco npany'ing draw 1ngs:- Figure 1 represents an end vlewojf aframe constructed in accordance with this f invention withthe churn inthe form of a barrel shown suspended therein in dotted lines, and frameshown collapsed in dotted lines,

Fig. 2 is aside .elevationthereof. shown in open-position ,in full linesand in partially collapsedposition indOtted lines, the churn .beingshown supported in said frame in .dots and dashesfand ,F i g. 3represents :a detail perspective iew .of onetof the bearings whichsupports the churn with the partsthereof arranged in jnxtaepositionreadyafor assembling.

In the embodiment illustrated, the frame constituting thiSziIlVBHfiQIlis p efe ably. constructed pf; angle iron and comprisesitwo A- shapedend members .1 and 2, the crossbar ,8 ofwhichis composedoftwo sections4. and

"'5 pivotally connected as shownat 6 anti with their outer endspivotally connectedto the s debars S and 9 of the frames 1 and 2.

flIhe pivotally connected ends of these sectlons 4 ando are arranged 1nlapplng relation with the horizontally disposed flange of one sectioncut awayat its pivoted end as shown at 7,1the edgeof said cut awayportlon be ng overlapped by thefiange'? on the other section so thatwhen these sections are arranged in longitudinal alinement as shown inFig. '1', 'theoverlapplngflange 7" will operate to hold the sectionsrigidly against furtherfldownward movement and yet permit the sectionsto open npwardlyinto folded position when the frame isto be collapsecbThe sidebars 8 and'9 of these A shaped frames areprovided at their lowerends with laterally extending surface engaging plates J10 and at theirupper ends which are piv otajlly connected with pint lereceiving'bearugs 11 which are made n the form of sections 12 and 18onecarried by one side-bar and the .otheriby the other side bar and eachhaving complementary hinge knuckles 14E fer hingedly connectingbars 8and'9 and .also the bearing sectionsrl2 and '13. These bearing se tionsare secured'to the side bars 8 and f9 byriveting orin any other'suitable manner and are provided at'th'eir upper ends V with re isteringsemicircular grooves 17 1 which formwhen t hese sections are broughttogether, a bore 718 to receive one of 'jthe pintles 19 of the churn orother vessel O to be suspended withinthe frame.

It is to beunderstood that thesej A shaped send membersare constructedesactlylalike and hence one'only has been described. in d al The endmembers, 1,.and2 of each frame are connected by diagonally disposedbraces 20 and 21 which are'preferably composed of angle iron, each haymga laterally extending flange. along one, side edge'thereof as is shownclearly, at 22 in Fig. 2. Each of these'braces is pivotally connected atits opposite ends with .one of the sidebars of; each end member 1 and '2and one of said braceshas'its .endsdisposed on the outer face of saidbars while the other is disposed 011 their inner faces asis' shownclearlyin ,Fig.' 2 withthe flanges 22 ofsaid'braces, one extending out-Qwardlyandthe other inwardly so that the tflansm oth "f e .ofthesebraceil b dis I and 15 through which thepintle'16 ispas sed posed adjacenteach other and avoid unnecessary spacing thereof. As shown in Fig. 2,brace is pivotally connected at its lower end with the inner face of theside bar 9 of the end member 1 and at its upper end .is pivotallyconnected with the inner face of the side bar 9 of the other end member2' while brace 21 is pivotally connected at its lower end with the outerface of the side bar 9 of member 2 and at its upper end with the outerface of the side bar 9 of member 1, said upper brace ends being'arrangedadjacent the upper ends of said side bars so that when the frame is inexpanded opera tive position it will be firmly braced throughout itsheight.

Each of these braces 20 and 21 is cornposed of two pivotallyconnectedsections as 23 and 24, the connected endsrof which are arranged inoverlapping relation in the same manner thatthe section ends of thecross bars 3 are connected, the flange 22 at the inner end of onesection being cut away and that of the adjacent end overlapping the cutaway portion so thatwhen the brace sections are in longitudinalalinement, this overlapping flange will operate to hold the bracesagainst further downward movement.

It will thus be seen that when the braces 20 and 21 are in openoperative position as shown in Fig. 2, and the sidebars 8 and 9 havebeen expanded and held in open position by the cross bars 3 as shown infull lines in Fig. 1, the frame is in position for supporting the churnbarrel C- or any other vessel to be supported thereby. In order thatthis churn may be mounted in said frame, the bearing sections 12 and 13are separated to receive the pintles 19 of the churn by first breakingthe joints of the cross bars 3 and moving the side bars 8 and 9 of thetwo A-shaped members toward each other a sufficient distance to causethe bearings to open at their upper ends as shown in dotted lines inFig.1 and when in this position the pintles may be lowered into saidbearings and the end members opened up into the position shown in fulllines in Fig. 1 whereby the bearing sections 12 and 13are closed aroundsaid pintles and afford a firm support for the churn.

After these members have been so positioned they are locked againstcollapse by means of a cross bar 25 which is pivotally connected at oneend with the lower end of one of the side bars of the A-shaped member 2and has detachable engagement at its other end with the correspondingside bar of the A-shaped member 1 as is shown clearly in Fig. 2. In thisfigure the cross bar-25 has its free end inturned to form a hook 26which is engaged with a slot 27 formed in said bar 9 of member 1 andwhen this bar 25 is so positioned, the frame is held against collapseand can only be folded after lifted from said frame and deposited at anysuitable point. The further collapse of the frame is accomplished bybringing the lower ends of said bars 8' and 9 of thetwo sections intocontact with each other and then breaking the joints in the sectionsofthe'bra'ces 20 and 21 and folding said braces upwardly as shown indottedlines in Fig. 2, the folding being continued'until said braces arein completely folded position and when in this position, the braces 20will be housed within the bars of the end members while the braces '21will be disposed on theouter face of said bars and lie in closeproximity thereto. It will thus be seen that the frame when so c0llapsedwillcoccupy a very small space and may be conveniently stored orshipped.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains and while I have described theprinciple of operation of the invention together with the device which Inow consider to be the best embodiment thereof, I desire to have itunderstood that the device shown is'mere'ly illustrative and that suchchanges may be made as are within the scope of the claimed invention.

I claim y '1. collapsible frame including foldable end members, foldablebracebars connecting said members, and a cross bar pivotally connectedat one end with one end member "and detachably engaged at its other endwith the other end member whereby the frame is heldoted to fold in onedirection, means for locking said sections against pivoting in theopposite direction, folding'brac'es connecting said end members, andmeans for locking said braces in open position;

3. A collapsible frame including 'A-shaped' end members, each composedof pivotally connected side bars with a cross bar conneotmgthem andcomposed of sections pivoted to fold upwardly, cooperating means on saidsections for locking them in 1ongitudinal alinement against downwardfolding, upwardly folding braces connecting said end members, means forlocking said braces against downward folding, and a cross bar detachablyconnecting said end members to hold the frame in operative position.

4. In a frame of the class described, a pair of A-shaped end members,the side bars of which are pivotally connected at their meeting ends andthe cross bars composed of pivotally connected sections and pivotallycopies of this patent may be obtained for five cents each, by addressingthe Commissioner of Patents,

connected with said side bars near their lower diverging ends, saidcross bars being foldable inwardly and held against outward folding,foldable braces connecting said end members, and means for locking saidbraces against folding. y

In testimony whereof I aifix my signature in presence of two witnesses.
